This is a lightly-edited transcript of an onstage conversation between Werner Herzog and Roger Ebert after the April 2004 screening of Herzog’s “Invincible” at Ebert’s Overlooked Film Festival at the University of Illinois at Urbana-Champaign. The film involves the story of a Jewish strong man hired to appear as an Aryan god in a vaudeville theater in Germany, at the time of the rise of the Nazi Party.
